The proposed project will develop and test a new CO2 capture technology for treating post-combustion emissions. This new solvent-based process couples the unique attributes of non-aqueous, CO2-binding organic liquids (CO2BOLs), with the newly discovered polarity-swing-assisted regeneration (PSAR) process that is unique to switchable ionic liquids. Combining this polarity assist with CO2BOLs is estimated to provide more than 42% energy savings over aque-ous alkanolamine systems. Further, the low regeneration temperatures of the proposed tech-nology also allows for unique energy integration techniques that can further improve this energy savings to more than 65%, such that parasitic load penalties of CO2 capture would be a fraction of current commercial systems.
